Filed: 1989-08-04
Abstract: PURPOSE:To cool furnace wall portions opposing to each other between upper leg portions by disposing water cooling pipe between the adjascent upper leg portions of a U-shaped iron core and directing cooling water to the water cooling pipe. CONSTITUTION:A water cooling pipe 8 is fixed to the surface of a stainless plate 7 on the side of the same possessing a bottom 7c such that a protrusion part 8a is fitted to a tooth part 7b.

Title: Manufacture of multiplex quantum well structure semiconductor laser
Inventor: SUGIMOTO MITSUNORI
IPC: H01S5/223
Filed: 1983-10-27
Abstract: PURPOSE:To enable to simply manufacture a multiplex quantum well structure semiconductor laser by a method wherein an evaporation source for a first material provided inclinably to the semiconductor substrate is utilized, and at the same time, the semiconductor substrate is made to revolve and the active region is formed by laminating alternately layers having a larger content of the first material and layers having a smaller content of the first material as a striped step difference part. CONSTITUTION:An Al evaporation source cell 32 installed inclinably to an n type GaAs substrate 20 is used only at a time when an active region 23a is grown. In case other layers other than the active region 23a are grown, the growths thereof are performed using an evaporating source cell installed almost vertically to the n type GaAs substrate 20 other than the Al evaporation source cell 32. Accordingly, other layers other than the active region 23a and a confinement region 23b, which is formed at the same time as a time when the active region 23a is formed, are almost uniformly grown in the film face of the n type GaAs substrate 20. However, in case the active region 23a is grown, the depositing rate of Al on a striped step difference 29 is changed according to positions of the substrate 20. On the other hand, in a substrate position 20b, AlGaAs is grown, because there is not at all that Al molecular beams are intercepted over the whole in the film face of the substrate 20. As a result, when the substrate 20 is made to revolve, GaAs and AlGaAs are automatically laminated on the step difference 29 according to positions of the substrate 20.

Abstract: PURPOSE:To make a circuit for separating a soft start circuit from a safety circuit unnecessary, by a method wherein the soft start circuit is connected to one side of a pair of transistor driving circuits while the safety circuit is connected to the remaining parts thereof. CONSTITUTION:A soft start circuit 8 is connected to the driving circuit of a transistor (Tr) Q1a between a pair of main transistors (Tr)s Q1a, Q1b while a safety circuit 7 is connected to the driving circuit of the (Tr) Q1 b. In the soft start circuit 8, the (Tr)s Q81, Q82 are put OFF until a time when the voltage of a capacitor C83 rises up sufficiently, the oscillating frequency of the invertor 4 is raised so as to be deviated from a resonance point whereby a current is reduced. In the safety circuit 7, the charging voltage of the capacitor C71 exceeds the Zener voltage of a zener diode ZD71 when the peak value of the voltage of a filter choke L31 becomes higher than a specified value, whereby the (Tr) Q72 is put ON and the oscillation is stopped through the (Tr)s Q73, Q71. The soft start circuit is separated from the safety circuit, therefore, there may be no interference.

SOLUTION: Stress sensing device 5 to 8 are attached respectively to support parts of respective axles 10 at a vehicle, i.e., to air suspensions 1, 2 at front wheels and the leaf-spring suspensions 3, 4 at rear wheels. Output signals of the stress sensing devices 5 to 8 are sent to a control unit 9, and the control unit 9 computes the output signals. The loaded weight of a load and the weight balance of the load as computed results are displayed on a display 11 and a display 12. At this time, the display 11 is used for a display inside the vehicle so as to display 'the total weight of the load' and the weight values of the load applied to the respective axles 10. The display 12 is used for a display outside the vehicle so as to be used, e.g. as a character display, and it displays that the load is proper and that the load is excessive.  Thereby, it is not required to move every vehicle to a place in which a gravimeter is installed, and the weight of the load can be measured precisely immediately after the load is placed.
